5.1 NORMAL START
1. Check the level of the oil in the tank.
2. Check that all the necessary gas, oil and water valves are open.
3. Start the lubricating oil pump motor.
4. Ensure the capacity control valve is in the fully unloaded position.
5. Start the drive unit and check that all gauges are indicating normal readings.
5.2 NORMAL STOP
1. Stop the drive unit.
2. After the compressor stops, the control system should be operated to move the slide valve
into the off load position unless the control system does this automatically.
3. After the compressor stops rotating, stop the lubricating oil pump motor.
4. Close all gas and water isolating valves.
The compressor is now ready for the next start up sequence.
NOTE: A log should be kept of the instrument readings so that deviations from normal running
conditions can be easily seen by the Engineer in charge of the installation.
